Summary

The Ins and Outs of Involuntary Part-time Employment

We develop an adjustment procedure to construct U.S. monthly time series of involuntary part-time employment stocks and ﬂows from 1976 until today. Armed with these new data, we provide a comprehensive account of the dynamics of involuntary part-time work. Transitions from full-time to involuntary part-time employment dom-inate this dynamics, spiking up at recessions’ onsets and persisting well into recovery periods. Weaknesses in job creation, on the other hand, contribute little to these ﬂuctuations. Our data and ﬁndings are relevant to inform a broader assessment of labor market performance and to develop models of cyclical labor adjustment.
